I use 2400 in 410. I've used 296/H110 also, but they don't do anything 2400 won't at a lower cost. Hull life is the same, although individual experience and/or perceptions seem to vary quite a bit on hull life observations. Personally, I don't use anything but AA hulls in 410. Use what you want, It's fine with me.
12 and 20 gauge Remington crimps last so long now that hull burn through is usually the reason for retirement, especially in 20 gauge. I keep hulls in batches by number of firings (although I don't actually count how many) and when a few burn through, I discard the batch. They are great component hulls, perhaps the best shell ever made. I fear our STS brass head is economically doomed however. Thus, I likely have accumulated a lifetime supply.
I finally had a Fiocchi 616 not fire also. It was just this year, although the primers were obtained 5 years ago. They are a good primer. I avoid Cheddite due to piercing in my Brownings.
No product is perfect, but I agree that modern shells and components are very good indeed.
